Diesel generator power shortage, load large automatic shutdown configuration troubleshooting a time 200KVA generator generator total less than 60 hours, when a load current of 120A outside the emergency generator will automatically shut down after a few hours of maintenance troubleshooting had finally been recovery. Symptom: normal engine start, idle properly. Together over the open peripheral load current from 0 to 120A, for about 1 minute until smoky engine speed drops down significantly. Failure Analysis: generator configured to 200KVA, carried the load current can reach 360A, 120A only now load automatically shut down the engine to move Cummins generator maintenance, obvious lack of engine power generator maintenance imports, may supply the oil part problem. Troubleshooting process: 1, the replacement of diesel generators and sediment filter core, restart the engine after correct assembly and maintenance of power generators, with load currents can reach 160A and then automatically shut down; 2, open play dumping sewage tank valve diesel found in sewage water large parts of the content, after the exclusion of water pollution discharge valve installed start the engine again, when negative energy up to 200A or down; 3, open the tank drain valve completely let go of all the diesel fuel tank, found that diesel impurities, dirt more. Washed with high-pressure pump gas tank, re-fueling (with gauze filter oil timber) flush tank back and forth and let go of oil contains impurities in the oil until the release of dirt is very clear and free of impurities. And then re-join the diesel (with a gauze filter when adding diesel), restart the engine, close the load switch open, current until 340A (when all possible load) in normal operation. Fault completely ruled out. Check the preparation before the diesel generator diesel generator is started before starting work is to ensure that its output is often only, while the diesel engine can normally start is the key to ensure that only regular work. The following combination of diesel engine starting conditions on the impact of the five cautions diesel generators running. 1. diesel engine starting conditions at start-power diesel generator maintenance, the cylinder should have plenty of fresh air and fuel supply system is working properly stretched, inside the cylinder must also have a higher temperature. In this case, after the diesel injector to spray mist into the combustion chamber, diesel engine can start normally. However, the temperature rises inside the cylinder of the piston in the cylinder must be repeated compression can be achieved. Diesel engine running at low speed, Wei and compression force inside the cylinder are low, the internal combustion leak also more internal fuel pump plunger velocity slower injector nor the technical requirements prescribed in the fog like the combustion chamber fuel injection. If the external environment, the benefits of the low, the lowest starting the engine speed must be increased, so as to achieve normal start creating sterile requirements. 2. Diesel not to visit until a dynamic process of moving earth for a task analysis of diesel engine starter is to give a certain torque diesel engine crankshaft, and the crankshaft speed to speed diesel engine starting over. Determine the difference between the speed of the crankshaft in torque and drag torque of the diesel engine starter itself. Torque starting means depends on the battery voltage, capacity and power starter. If the battery voltage or less than the required capacity of the technical requirements, the diesel engine can not be carried starter; starter if the power is too small, the same can not enable normal starting of diesel engine. Soil resistance moment to decide when to start the diesel engine A degree oil, friction and gas inside the cylinder diesel engine compression force moving parts. So, in a different quarter of 17 to choose different brands of oil. Starting in the winter when the diesel engine, in individual cases but also for decompression starting to reduce the starting resistance of the diesel engine.
